Simulation of Different Acoustic Lecture Room Designs

Advanced Materials Research, 2014
Room acoustics of the internal environment is among others an important part of good design. The paper deals with the simulation of lecture room acoustic structural modifications. In specific lecture room was measured reverberation time of the current state.

Simulating Acoustics of a Room Using MATLAB

2019 22nd International Conference on Control Systems and Computer Science (CSCS), 2019
A speech given inside a big room will always be distorted by the undesirable effect of echo. Taking advantage of the linearities of sound reflections, we propose a method for simulating voices affected by reverberation in different rooms. Our approach is based on the Room Impulse Response (RIR) method and our technique reveals an easy and intuitive way

Consulting applications for an acoustical simulation room.

The Journal of the Acoustical Society of America, 1992
An acoustical simulation room was constructed for acoustical consulting use. The design criteria called for a space that could simulate the background noise, reverberation, spectral, time based, and directional response of proposed and existing spaces. Readily available professional audio and acoustical products were utilized for implementation into a ...

Investigating Room Acoustics by Simulations and Measurements

Noise & Vibration Worldwide, 2013
Measurements in room acoustics are often used as the true reference of reality, while simulations are considered to be only a crude representation of it. However, both approaches have their own challenges and limitations, so measuring an impulse response and deriving room acoustic parameters correctly may be more difficult than it appears at first ...

Recent Progress in Room Acoustical Computer Simulations

Building Acoustics, 1997
In the last decade computer simulations of sound fields in rooms have been developed for application in research and consulting. Some programs are commercially available. Most computer models are based on geometrical room acoustics and/or on statistical (radiosity) methods, thus not including wave phenomena such as diffraction.

Adaptive room acoustic response simulation: a virtual 3D application

2003 IEEE XIII Workshop on Neural Networks for Signal Processing (IEEE Cat. No.03TH8718), 2003
In this paper we propose a method to simulate a 3D acoustical environment in which sound sources are positioned in well defined sides. Our method is real-time applications oriented, due to the low computational cost of the implemented operations. The spatial position that the human brain assigns to a sound is influenced mainly by the differences ...

Room Acoustics – Fundamentals and Computer Simulation

2018
In room acoustics analytical formulas and computer simulations can be used to predict the acoustics of spaces, not only in terms of reverberation but other perceptual aspects, too, which are related to the perception of music or speech. In this context the room impulse response is the function of main interest. It can be measured by using sophisticated

Directional source modeling in wave-based room acoustics simulation

2017 IEEE Workshop on Applications of Signal Processing to Audio and Acoustics (WASPAA), 2017
Wave-based modeling in room acoustics and virtualisation applications constitutes an alternative to geometric or ray-based approaches; finite difference time domain (FDTD) methods, defined over regular grids, are an excellent match to parallel architectures.

Modeling binaural receivers in finite difference simulation of room acoustics

The Journal of the Acoustical Society of America, 2013
Binaural room impulse responses are important for auralization as well as for objective research in room acoustics. In geometrical room simulation methods, obtaining such responses is easily achieved by convolving each computed reflection tap with a corresponding pre-measured angle-dependent head-related impulse response.

Level of detail in room-acoustic simulation

The Journal of the Acoustical Society of America, 2019
The quality of present-day room acoustic simulations depends on the quality of the boundary conditions and of the underlying CAD room models. A “high-resolution” room model does not mean that it needs to have a visually perfect geometrical fine structure.
